Callback Tones

This plugin provides three different modes to access a webcam through a small API directly with javascript - or more precisely jQuery. Thus, it is possible to bring the image on a Canvas (callback mode), to store the image on the server (save mode) and to stream the live image of the Flash...

Compute the discrete Fourier transform at specified frequencies, not using fft.Why one may need this?(1) MATLAB fft function computes the amplitude of signals only (no phase).(2) Once having the recorded time-series data, one often uses fft to do the spectral analysis. However, the frequency set...

EOG Correction program is used to work out the amount of ocular potential recorded by the electroencephalograph [EEG] (as a proportion of the potentials recorded by the electrooculograph [EOG]), and to subtract this from the EEG. By doing this we are able to reduce the effect of ocular potentials...

UICOMPONENT is intended as a direct replacement of Matlab's built-in UICONTROL and JAVACOMPONENT functions. It accepts all parameters and styles that UICONTROL accepts, as well as any other displayable Java (Swing/AWT) component class. The calling convention and syntax of UICONTROL were preserved...

For the description, I took the abstract of the original publication:"A special set of computer-generated complex tones is shown to lead to a complete breakdown of transitivity in judgments of relative pitch. Indeed, the tones can be represented as equally spaced points around a circle in such a...

Tired of using USERDATA or GUIDATA calls to share data between callbacks in GUIDE? Nested callbacks are the answer. A nested function can "see" all the data that the top level function can. You therefore no longer need to painstakingly save or pass data for later use.Unfortunately, up until now...
